三麦亩产低而不稳,主要受气候影响,如遇秋雨连绵既难种,又难收。为了解决这一问题,我场自六十年代初就学习上海的套播麦种植方法。由于套播麦存在保苗、壮苗和收获前茬等矛盾,无法大面积推广。七十年代后期又试验灭茬免耕获得成功。1980年全场灭茬免耕麦面积已达6000多亩,占三麦总播面积55%以上。但这种免耕方法,需正常的气候条件、田面干燥, Three acres of low and unsteady yield per mu, mainly affected by the weather, in case of autumn and rolling both difficult species, and hard to close. In order to solve this problem, I learned Shanghai’s planted wheat planting methods since the early 1960s. Due to the existence of seedling wheat seedlings, strong seedlings and harvest before the conflict and other conflicts, can not be large-scale promotion. In the late seventies and experimenting with stubble tillage was successful. In 1980 the entire field of stubble tillage wheat has reached 6,000 acres, accounting for more than 55% of the total sowing area of ​​three wheat. However, this no-till method requires normal climatic conditions, dry field,
